Title: Method for visual delivery to a caller of selected information associated with a telephone number in an advanced intelligent network via a public switch telephone network
Inventor: RAJI ALEXANDER DAVID
IPC: H04Q3/00
Filed: 1998-06-15
Abstract: A method for a telecommunication subscriber to obtain information associated with another telecommunication subscriber using telecommunications terminating equipment with data receipt and visual display capability, such as an analog display service interface compatible telephone, and an advanced intelligent network (AIN), accessible through a public switch telephone network (PSTN). In the method, a caller sends a first communication to the PSTN including an information retrieval service number. In response to receiving the first communication, the AIN, through the PSTN, sends a message to the caller prompting the caller to communicate a subject telephone number. The caller, in response sends a second communication including the subject telephone number. In response to receiving the second communication, the selected data is retrieved from a database and then sent by the PSTN to the caller's telecommunications terminating equipment in a response message for visual display of the data.

Title: Process for producing batches of rubber-based composition
Inventor: GRENIER DANIEL
IPC: C08J11/06
Filed: 1998-08-19
Abstract: Processes for the batch production of rubber-based compositions capable of being shaped and shaped articles made thereof. They include a step of high intensity mixing cured rubber particles with other selected compounds into a closed mixing chamber provided on a high intensity mixer including a central shaft having mixing blades. Through high speed rotation of the shaft, blade tip speed above about 20 meter/s are obtained to intensively mix and thermokinetically heat the batch of mixable material, whose temperature is continuously monitored.      Discharge of the batch from the mixing chamber takes place when the temperature is considered to have reached a reference value ensuring a substantially uniform mix of the rubber material and added compounds, to produce the rubber-based composition. According to a first preferred embodiment, cured rubber is fed into the mixing chamber with a resinous material, and discharge occurs at a temperature ensuring a substantially uniform mix of the rubber material in a matrix of resinous material to produce the rubber-based composition, which can be then shaped without any further heating. According to a second preferred embodiment, a curing agent is added to the cured rubber particles, and the batch is discharged from the mixing chamber when the temperature reaches a reference value ensuring a substantially uniform mix of the cured rubber material with the curing agent without causing a significant further curing, to produce a rubber-based composition capable of being heat-shaped. Other preferred embodiments using a reactive polymeric binding agent and a bonding agent are described.

Abstract: An ergonomic handgrip for use as a fitness grip and also for use with a wide variety of devices and equipment such as ski poles and bicycle handlebars by being incorporated into the handle portion thereof. In a basic illustrated form, the grip has an elongated base with a central axis and opposed ends, the upper of which ends includes a thumb support. The front face is sculptured or contoured for finger reception, so that, when gripped, the thumb is supported in a bent position and the hand and wrist are in a neutral position. In such neutral position the hand is not cocked or hyperextended, but rather the hand is generally aligned with the forearm. Further, the end of the base opposite the thumb support, i.e., the lower end, is reduced in size to allow disproportionately more contraction of the lowermost two fingers, and primarily the lowermost or little finger. When the grip is used as a standalone handgrip or when another element does not pass through the lower end thereof, the lower end includes a thickened inverted arcuate section having a central bore, the arcuate section being spaced in from the edges of the lower end. A preferred version includes an elongated recess within the base on the side directed toward the palm of the hand. The grip can also be employed by being incorporated into the handle or shaft of a hammer or mallet.
